FRANK L. VAUGHAN AND JAMES n. MQKENZIE, or RoonEsTER, NEW YORK.-

cARBURETER.

county of Monroe` and State of New York,

haveinvented certain new and useful Improvements in Carbureters, of which the following is a specification.

'This invention relates to carbureters and more particularly to those ofthe mixing.

and has for its object to provide- .valve type,

- a structure of this kindin which the valve proper will be operated by the suction of the engine, and in which the gasolene supply will be controlled by the valve, the arrangement being such that `gasolene will be admitted to the aspirator in advanceof the tion.

Auncharged air, a particular object being to provide a structure in .which v4the movement of the -gasolene controlling valve will be in increased ratio to the valve proper, termed the puppet valve in the following descrip- Other objects and advantages willbe apparent from the following description and it will be understood thatl changes in '.thej

specific structure shown and -vdescribed may be made within thefscope of the mvention.

1s a parts in active position.

Referring now to the drawings there is shown a. vertically extending pipe 5, having a central enlargement 6 in which-there is located a transversely extending hanger 7,

having a .pair of levers 8 pivoted therein'. These-levers include fingers 9 extending toward each other from the pivot points 10 of thelevers, and the levers also include downwardly extending .wei hted portions 11, having diagonal lower e ges -12 extending upwardly and inwardly in convergent relation to receive thereagainst the edge porlevers 8 and movable tions of a puppet valve 13 located below the vertically into and out of .a sat lll.

It will be seen 'frorn'the drawings that when the valve 13 is raised, its engagement with the diagonal faces `12 will result in 'ment, a needle valve carried byI the valve upward movement of the levers 8 with conclaims-A without departing-from the s piritf ofthe` lSpecitlcation of Letters Patent. Application led December 14, 1908. Serial No. 467,454.

sequent downward movement of the lingers l9 Wl'nch carry therewith the vertically Aextending stem lof a needle valve v16, which has vertically spaced ang'es 17 between 60 which the fingers are engaged. The needle valve 16 works in a seat 18.formed in a member 19 extending horizontally into the i pipe 5 and having a'gasolene passage 20 communicating with the v alve seat 18. A

set valve21 is of gasolene through the A-s will be obser/ed from the foregoing,

provided -to govern the flow passage 20.

when the valve 16 is moved downwardly byportionof the pipe V5 which the levers 8, the gasolene will be permitted?o flow :trom'the memberlQ into the upper plrator. As indicated, the puppet valve 13 is prO- vided with a'dpendin shank 22 which has 75 a chamber .23

erewit in opening through.

the upperface ofthe valve,` and this cham-- ber receives the lower portion ofthe valve stem 15, this "valve 'stem. thus acting as a guide for the to limit the upward movement. of the valveA l' -13 through engagement of the lower-end of the stem 15 against the bottom of the p as-l sage 23.

f A.AS lshown in the drawings, lthe pipe is prlo- *A videdwith a throttle 24 at its lower portion and with anl attaching flange' 25 at its upper '.portion. 1

l What lisclaim'ed is v.

1. .A carbureter comprising a pipe, an air' 90 valve seat in' the pipe, an air valve arranged 11e normally 1n the valve seat,levers ivoted in the 4pipein parallel relation, sai levers being located in position for engagenient -by the valve when thelv valve is moved 95 into open positionsaid levers having later-A ally extending ingersfan oil control needle valve includinga stem, carried by the fstem,

and spaced flanges said lingers'being engaged between the anges said levers being weighted to hold. them normally with valve stem vin valve. 2. In a carbureter, the combinationwith a the position to close the needle pipe of a vertically extending valve stem 195 slidably mounted in the pipe, levers -pivoted within the pipe,

'connections between the Ile- 'vers andthe valve stem for movement of the valve stem when the leversare moved, said:

levers being weighted to hold the valve stem normally at the upward limit of its movepuppet valve 13, and as a stop 8.0 l

lstenf,` a member having a seat dor-'the' need-e ing with the seat, apuppet valve located below the levers Aand arranged for engagement of' the .levers andjor movement thereof out'o'f ltheirnormal positions when the pnppet valveis opened, said puppet valve Y' havingapassage in which the valve stem is 10 sldably engaged.

In testimony whereof We aifx our signatures, in presence of two witnesses.
